This invention relates to attachments for oil cans, and more particularly to the provision of an. oil seal for preventing a back flow of lubricant from the oil hole in which '5 the spout of the oil can is inserted.-

Among the objects of my inventionare to provide an oil seal or attachment for 01]. cans of novel construction and adapted to be deprovide a new and improved construction of oil seal or attachment for oil cans of novel shape or configuration; further to provide an 1 oil seal or attachment that is interchangeable so that either end thereof is adapted for engagement with the oil hole; further to provide an oil seal or attachment adapted to be used as a stopper or seal for the end of the oil spout when the oil can is not in use further to providean oil seal orattachment of maximum simplicity, efiiciency, economy, and ease of operation; and such further obiiects, advantages and capabilities as will 80 ater more fully appear.

My invention further resides in the combination, construction and arrangement of ing, and while I have shown therein a preferred embodiment, I desire it to be understood that the same is susceptible of modification and change without departing from the spirit of my invention.

Qne form of the invention is shown in the.

accompanying drawing and the views thereof are as follows:

In thedrawing: 1 Fig. 1 is a view in side elevation of an oil can with an attachment thereon embodying my invention. v

Fig. 2 is a fragmentary vertical cross sectional viewon line 22 of Fig. 1. Fig. 3 is a horizontal cross-sectional view on the line 3-3 of Fig. 1.

Fig. 4 is a fragmentary cross-sectional View of my attachment or oil seal as applied to the end of the spout of an oil can for preventing leakage when such oil can is not in use.

Referring to the form of inventionv illustrated in the drawing, the attachment or oil seal or fitting is designated generally at 1, and in Fig. 1 isshown as applied to the end of an oil spout 2 of an oil can 3. My attach-. ment or oil seal comprises an elongated body of rubber composition, or other suitable material having a reasonable amount of elasticity so that with a small amount of pressure, such body may readily adjust itself to the inner circumference of an oil hole so as to prevent any leakage therefrom. The

upper and lower portions of the member 1 i are provided with curved faces 4 and 5 respectively, the lower portion 5 being further provided with a bead 6 as more clearly shown in Fig. 3. A circular opening 7 passes longitudinally through the center of such attachment or oil seal for allowing the same to be readily inserted over the upper end of the spout-.2. The purpose of the head 6 is to strengthen the lower portion of theattachment so as to prevent the same from splitting while it is being placed over the oil spout.

Any other means might be employed for preventing splitting of the attachment, if desired. A sleeve, for instance, might be arranged about the ends of the same. parts illustrated in the accompanying draw- The central portion 8 of the member 1 is in the form of a polygon, or, as more clearly shown in Fig. 3 of the drawing, is in the form of a hexagon, although any number of sides may be provided. The purpose of thisportion 8 is for facilitatin the attaching or removal of the oil seal, it being understood that the opening in the member 1 makes a sufficiently tight connection with the upper end of the oil spout so that the member 1 cannot be readily attached or removed except by turning such member.

An opening 9 may be provided. in one of the sides of the polygon. This opening is adapted to fit over the upper end of the oil spout, as more clearly disclosed in Fig. 4. When the member 1 is inserted or placed in this position shown in Fig. 4, it provides a seal or stopper for preventing the leakage of any oil from the can when the same is not in use. a

In operation, the attachment or oil seal is forced over the end of the oil spout to a position substantially as shown in Fig. 1, the upper end thereof being spaced from the upper end of the oil spout. As stated above,

the attaching of the oil seal to the position shown in Fig. 1 is accomplished by a turning movement of the member. This turning movement is greatly facilitated by the provision of the polygonal portion 8 of the attachment. When it is desired to forcea lubricant into an oil hole, the end of the oil spout is inserted into such hole' to a depth where the rounded portion 4 contacts with the inner circumference of the oil hole, and due to the resiliency of the material of which the attachment is formed, the-rounded face 4 will adjust itself to the inner circumference of the oil hole and form a tight seal therewith, preventing the leakage of any oil that is being forced into such hole. As stated above, either the rounded portion or face 4 or 5 can be used as the upper face for providing a contacting engagement with the oil hole, althoughwhen the face 5 is used for such purpose, the oil hole should have a diameter greater than the diameter of the head 6 of such face.

The portion of the spout of the lubricator extending beyond the end 4 of the member 1 serves as a pilot in applying the lubricator or oil can to an oil orifice or hole for lubricating pur oses.

The 'tting or oil seal is so applied. to the spout as to lie inwardly of, or behind the discharge orifice of the spout. That portion of the spout structure ahead, or in front, of the fitting constitutes a pilot for use in applying the oil-can or lubricator to an oil hole or orifice.

When the oil can or lubricator is applied to an oil hole or orifice, it is pressed against the material defining such hole or orifice in substantiallyend-tq-end contact, and the rewise compressed to seal the hole or orifice against spillage of lubricant between the oil hole and lubricator spout. v

It will thus be seen that I have provided an attachment or oil seal for oil cans'that will make a tight connection with the oil hole when the lubricant is being forced into such hole. The rounded contours of the faces will adjust themselves to the hole and prevent the ,leakage of any lubricanttherefrom.
